Interesting opinion on the food and drug industry

As usual was watching TV during lunch, and happened to see this American program with a special guest talking about a book called 'The Natural Cures They Don't Want You To Know'. According to the TV program guest, the food and drug industry simply doesn't want ppl to be healthy because otherwise their profits would be severely affected. Take a simple example. We are always encouraged to 'eat right'. However, many food labelled 'Diet' nowadays actually contain ingredients that are added specifically to increase appetite, to make ppl hungier, and inevitably to make ppl fat. Why? The fatter one gets, the more he/she would eat, which means more profits for the food industry. As for the drug industry, the black scenes are even worse, according to the program guest. The American authority that regulates the drug industry explicitly states that 'Nothing can prevent, cure, or diagnose a disease unless it is a drug'. Along with this rule, they are classifying more and more illnesses as 'disease'. Even obesity is a disease. The result? More and more natural cures (non-drugs) are eliminated from ppl's knowledge. Manufactures of those natural cures cannot state that those things have curing effect to particular diseases because if they do, they are effectively selling drugs without a license, which is illegal. And a drug license can cost as much as hudrends of millions of dollars. In one word, more and more illnesses can be cured only by drugs, as ppl know, because they will never get to know about other natural cures. The direct consequence is higher demand for drugs, which again represents $$ to the drug industry.
Pretty insightful and interesting theories.
